H264 issue in fedora

today i find a issue that i cant play some videos on youtube in firefox i have installed firefox from flathub but it also same h264 is not there in the extension area but when i download firefox from other source like snap it workded and it was installed and active by default

i spin a ubuntu vm and look that snap have that when i install flatpak on ubuntu it was also active what wrong in fedora
i have also checked ultramarine and there was no issues as well it was said h264 will be downloaded in sometime and it downloaded
here what i saw in fedora when i install from flathub flatpak it was disabled

Added firefox, flathub, h264

I think this is not the Flatpak firefox, you seem to launch the Fedora Firefox instead.

If you dont mind, do sudo dnf remove firefox firefox-langpacks.

Or install libavcodec-freeworld from rpmfusion, which inclused the real h264.

You can verify that you use the flathub firefox by running it from the terminal

flatpak run org.mozilla.firefox &

Added openh264

Or, it is just in the process of installing, as said on the popup.

Again, the default way to get more info


or if you really use the flatpak

flatpak run org.mozilla.firefox

i am on silverblue this really a big issue
that enabling that does not solve this issue

You didnt answer any question I asked. Silverblue is an important info, but the preinstalled codecs are the same

Added silverblue

In addition to what been asked can you post:
flatpak list
